COMPOSITION FOR MASSING FINE IRON ORE AND PROCESS OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 588,792, dated August 24, 1897.

Application filed May 19, 1897. Serial No. 637,275. (No specimens.)

To all whom it may concern:

Be it known that I, J ULIUS J ACOB OZEPULL,

a subject of the King of Prussia, Emperor of.

Germany, residing at Lancaster, in the county of Lancaster, State of Pennsylvania, have invented certain Improvements in Compositions for Massing Fine Iron Ores and in the Processes of Making the Same, of which the following is a specification.

This invention relates to improvements in compositions for massing concentrates, downcome-dust, flue-dust, and other kinds of fine iron ores into masses or bricks and in processes of making the same; and the object of the improvements is to bind ores of that character into compact masses, so that when fed to or when in the furnace they cannot be blown therefrom by the blast.

My composition consists of the following ingredients combined in about the proportions statedviz., fine or comminuted iron ore, one ton; clay, pulverized, one hundred pounds; glue, liquid five pounds.

I do not restrict myself to the proportions stated, as with various kinds of ore and With ores of different degrees of fineness it may be found best to modify the proportions of clay and glue.

In combining the three ingredients, the ore, the clay, and the glue, the ore and the clay are first thoroughly mixed together and then the glue is gradually added and stirred into or with the ore and the clay. After the three ingredients are mixed the mass will be in about the condition of slightly-moistened sand. The compound is then placed in molds and subjected to pressure, after which it is removed from the molds and dried-preferably air-dried. The pressure should be continued merely long enough for the clay and the glue to thoroughly bind the particles of ore together.

If preferable, when the proportion of glue is reduced the masses may be dried by baking or by being passed through a hot-air chamber.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A compound of the character described, consisting of fine or comminuted ore,.pulverized clay, and liquid glue, substantially as set forth. 7

2. The process of preparing fine or comminuted ore, consisting in commingling the ore with pulverized clay, moistenin g the compound With liquid glue, and then compacting this composition under pressure to form masses, substantially as specified.

3. The process of preparing fine or comminuted ore, consisting in commingling the ore With pulverized clay, moistening the compound with liquid glue, compacting this composition under pressure to form masses, and then baking said masses, for the purpose 65 specified.
